This paper aims to provide a comparative study between Vietnam and Indonesia in terms of policy and implementation of solar power plant development to date. The methodology that the authors use in this study is a qualitative research with a descriptive approach to. . Viet Nam recorded the largest surge in solar and wind energy capacity in Southeast Asia, reaching 19,501 megawatts (MW). This achievement makes it a pioneer of clean energy transition in the region, as well as a challenge for neighboring countries such as Indonesia. Solar energy is one of the. . At present, Vietnam has succeeded in becoming the leading country in ASEAN in the solar power development sector in order to meet its electricity needs and also in order to reduce carbon emissions. Indonesia is one of the countries that has ratified the agreement has made a "grand strategy" for the. . The new initiative features plans for 80 GW of 1 MW solar minigrids with accompanying battery energy storage, to be deployed across 80,000 villages, alongside 20 GW of centralized solar power plants. The program plans to build 80 GW of solar power plants and 320 GWh of Battery Energy Storage System (BESS) to be managed by the Merah Putih Village Cooperative (KDMP) in 80,000 villages, and 20 GW of. . Indonesia, an archipelago forming over 17,000 islands, is rich in natural resources and has as much solar potential as it does challenges.
